EDGE QR^TM

Effective Destruction of Gaseous Emissions

"Quick Response" Flameless Thermal Oxidizer for Chlorinated VOCs, High VOC Concentrations and Continuous or Batch Chemical Processing.

FLAMELESS THERMAL OXIDATION
EDGE QR Oxidizers employ a patented Flameless Thermal Oxidation (FTO) technology based on PYROCORE surface-stabilized combustion burners. The burner is constructed as a porous ceramic tube, installed in a larger diameter steel casing. VOC laden air and fuel are mixed together and flow through the porous ceramic tube from the outside-in, such that VOCs are oxidized on the inner surface of the ceramic cylinder.

Looking down inside of the ceramic tube, the distinctive appearance of the burner is a hollow cavity with a uniform incandescent glow without visible flames. These systems are uniquely designed to handle high concentration VOCs in continuous or rapidly varying batch processes. The proprietary ceramic construction is especially suited to handle hot acid gases typically formed by the treatment of chlorinated or other halogenated VOCs.

AIR AND WET QUENCH
Air or Water Quench exhaust systems are integrated into every EDGE QR Flameless Thermal Oxidizer so that lower cost, readily available materials can be used in construction of stacks and acid gas scrubbers.

ACID GAS SCRUBBER
For treating chlorinated VOCs and the resulting acid gas by-products, ALZETA offers fully integrated packed tower scrubbers, process blowers, and stacks, all constructed of corrosion resistant FRP materials. These systems include pH controllers with chemical storage and feed systems, and all necessary pumps, piping, and instrumentation.

HEAT EXCHANGER
To minimize operating costs, ALZETA offers recuperative heat exchange systems that reduce fuel burn by capturing energy from the hot oxidizer exhaust. With both shell and tube and plate type heat exchangers available, ALZETA engineers select the optimal choice of heat recovery to reduce operating costs & maintenance expense.

CONTROLS
"Reliability" is the trademark of every ALZETA System, depending on proven control components and instrumentation. When required, ALZETA control engineers also offer custom and integrated design features with PLC/DCS based controls, feed-forward process monitoring systems, and redundancy design.

PERFORMANCE BENEFITS

• Ultra-High Destruction/Removal Efficiency - up to 99.9999% demonstrated
